The boron interferes directly in the development and the growth of new cells. Its most known role is the one on the plant fertility and fecundity. It’s a critical element for many crops.
The copper is an enzyme component and, as catalyser, i tinfluences the carbohydrate and nitrogen metabolism. It especially supports the ear fertility cereals.
The iron supports the chlorophyll synthesis and it’s a component of some enzymes. It carries out many functions, such as energy transportation. The deficiency risk is very big in high pH soils.
The manganese is a catalyser of the chlorophyll synthesis and supports the nitrogen dynamics within the plant. That element is less mobile in the plant and the deficiency appears first on the young leaves.
The molybdenum supports the Nitrogen and Phosphorus uptake. Its role is also essential on the symbiotic nitrogen fixation by the leguminous plants. Acid soils may cause a molybdenum deficiency.
The zinc is an activator of various enzymes and it has a direct impact on the chlorophyllformation, the growth regulation and the protein synthesis. In case of deficiency, an interveinal chlorosis of the new leaves can pop up.
